based on the VIN sequence and SPD for crown coupe package you listed, are those the only ones we know of that have surfaced with an owner who cared about the limited production to join in our discussions? I am glad to now be the highest VIN of the crown coupe packages until and unless someone else chimes in with their data.Your car:
Sequential Production Number (SPN): 201437
Scheduled Production Date (SPD): 530
Comparing this to my modest data base of 1974 East Jefferson-produced cars, I get the following.
East Jefferson also produced Chryslers (New Yorker and Newport)
and Plymouth/Dodge/Chrysler station wagons. Those all contribute to the SPN value.
The highest SPN at East Jefferson is 222311, a Newport, SPD 722, MDH 071008. A still higher SPD, for another Newport, is 724. So they kept planning and producing C-bodies well into July, 1974.
Restricting this to Imperials, the picture is somewhat different. The highest SPN I have is 198301, SPD 513. This one also came with the Crown Coupe package.
So your 201437 stands out in this data base as the highest SPN known for a 1974 Imperial.
Your go-to page is <1974 - 1975 (Chrysler) Imperial WPC News Article> where it reads: "The 1974 Imperial was introduced on September 25, 1973, and the last 1974 Imperial was assembled on July 3, 1974". No idea whether "assembled" refers to the SPD or the MDH, as these things tend to get mixed up in the mind of some enthusiasts.
